Abstract

A bicycle operating device comprises a base member, an operating member, a wireless communicator, and a power supply. The base member includes a first end to be mounted to a bicycle handlebar and a second end opposite to the first end. The operating member is pivotally coupled to the base member about a first pivot axis. The electrical switch is to be activated by an input operation from a user. The wireless communicator is electrically connected to the electrical switch to wirelessly transmit a signal to an additional component in response to the input operation. The power supply is electrically connected to the wireless communicator to supply electrical power to the wireless communicator. The wireless communicator and the power supply are at least partially overlap with each other when viewed from a direction perpendicular to the first pivot axis.
